Does the DH61BE MoBo have an unusual shutdown sequence?
Seems like the fans and HD's click off first, one at a time, while the WinXp "windows in now shutting off" screen is still present. Never had one do that before. Usually, the monitor clicks off first, then the HD's, fans etc.
The issue you are experiencing could be related to the Operating System since Windows* XP is not a supported platform for this motherboard. We recommend testing with a fully compatible Operating System to properly narrow the issue:
